nNrTnn STATES ROBERT F. CORNEIL, OF PHILLIPSBURG, MONTANA,

CHURN.

To all whom it may concern: f

Be it'known tha-tI, ROBERT F. CORNEIL, a citizen of the United States, residing at Phillipsburg, in the county of Granite and State of Montana, have invented certain new and useful Improvements in Churns, and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specication,

and the gures of reference marked thereon.

My invention relates to churns of the general ty e of the one for which I have obtained etters Patent No.776,4196, Dec.

6, 1904, in which the churn body or box is suspended by trunnions andvbelts from a rocking frame, the rocking or oscillating of the frame to and fro causing a rapid revolution of the churn box or body iirst in one direction and then in the other, and the object of my invention is to simplify and otherwise improve the construction of churns of this type, and especially to enable the frame to be folded into small compass,

so that when the churn is not in use it will require but little space for storage, and for the attainment of the objects of my invention said invention consists in the churn having the construction substantially as hereinafter specified and claimed.

In the accompanying drawings, Figure 1 is a perspective view ofthe churn embodying my invention, shown in position for use; Fig. 2 a side elevation thereof with the frame shown in its folded up'or closed condition; Fig. 3 a perspective view of one of the trunnions,l and Fig. 4 a perspective view of one of the belt clamps.

The frame of my churn consists essentially of several, preferably two, semicircular rockers each'formed of two similar sections or halves hinged together by a hinge 11, the corresponding or opposite sections of the two rockers beingconnected by several, preferably two, transverse bars 12 and 13, respectively, the former being a short distance from the hinged connection between the two sections of a rocker, and the latter being preferably at the upper ends thereof, these cross bars being united to the rockers by nails, bolts, or in any desired manner. This produces a light but amply strong frame, which upon the hinged connections between the rocker sections may be opened out into the semicircular form as illustrated in Fig. l, but

closed up in'the compact state illustrated in Fig. 2. For holdlng and bracing the frame in its extended position for use, I employ for each rocker a brace bar consist1ngof two members 14 that are hinged together by a hinge 15 at one end, and each of which members at its opposite end is pivoted `by a hinge 16 to a rocker section, the middle hinge being below the brace bar, and the hinges at the extremity being above the same. When the rockers are opened out to their semi-circular position for use, the members of each brace bar are in a straight line to each other, their ends abutting against each other and against the rockers so that the rocker sections are thereby rigidly sustained or braced against any collapsing or closing tendency, and it is only by breaking the joint between the members of the brace bar by lifting the latter at the hinge 15 that the rocker sections can be swung in toward each other for closing the frame.

The churn .body is preferably in the, form yof a rectangular box 17, having centrally located on opposite sides two trunnions by means of which the box is rotatably suspended by two pairs of straps or belts 18, a pair being attached to each trunnion and extended therefrom in opposite directions, one belt of the pair being attached at its end to one crossbar 13 and the other belt at its opposite end to the other cross bar 13, the arrangement being such that when the rockers are swung in one direction, the churn body will rapidly revolve, rolling u on the trunnions, the belts running in the direction in which the churn body moves, and the other belts unwind. Each trunnion consists of a metal tube 19, which at one end has several radially projecting feet 20 by which `it is secured to the churn box by means of screws or bolts or other fastening devices passing` into the side of the churn body. Filling the tube is a round block 21 and there is a diametrically extending slot in both the block and the tube, and in the slot is placed the looped orl overlapped/end of each belt or strap, and it is there securely fastened by means of a pin 22 that is passed through the loop at the turn or'bend between one side of the filling block and the tube so as to make a thickness at this point greater than the Width of the slot, and thereby the belt or strap is firmly secured in place. The other end of each strap is fastened to the cross bar 13 by a clamping bar 23, which binds the strap against the cross bar 13, and on opposite sides of the strap is secured to the cross bar by screws or bolts, and in order to afford a tight grip on the strap, the strap-engaging side of the clamping bar is corrugated or roughened, and if desired, the strap-engag= ing surface of the cross bar 13 may be similarly formed. It will be seen that for the purpose of adjusting this strap, it is necessary merely to loosen the clamping bar-holding screws or bolts, and then slip the strap through to the desired point and again tighten up the screws or bolts. This constitutes a very simple and easily mani} iulated belteholding means.

Thechurn box has a removable cover 24 which is tightly held in place by means of two similar bails 25 composed of a cross bar adapted to extend over the top, in which are threaded two thumb screws for engagement with the top, and two end or side bars that are pivotally connected to the ends of a strap 26 of some suitable metal or other strong material, which extends over the ends of the churn box and across the bottom thereof. The top of the churn body has preferably metal straps 27 situated for the end of the thumb screws to impinge upon when the screws clamp the top to the churn box. The bails when swung to release the top, move outward toward the supporting straps at one side, and they engage and rest upon the straps, as is illustrated in the case of one bail in Fig. 1, and thereby serve as stops or brakes to prevent the accidental turning of the churn when the cover is removed to give access to the interior thereof, and so prevent the spilling of the churn contents. in order to make a perfectly tight joint between the lid or cover and the box, a gasket 28 is emplo'yed that may consist of a strip of rubber embedded in a groove either in the churn box or in the lid or cover.

The churn box is provided with a draw-ofi cock or faucet 29 for the removal of botten milk, and in the cover or lid l provide a stop cock 30 to enable gas to be discharged from the churn body.

It will be aplparent that by my invention a strong and ight supporting structure is employed that may be folded into very small compass, and the churn may be very easily operated, and there is nothing that can be very easily broken or gotten out of order.

l, of course, do not limit myself to the precise details of construction shown and described, and i do not limit myself to the employment of my ideas in a churn, because, for example, a washing machine might be constructed t0 embody the principles of my invention, nor do l limit myself to a churn body consisting of a rectangular box, al-

though i prefer a rectangular or cylindrical, or other balanced form of box, because such a form is better adapted to this type of machine, and other forms of box may be employed without departure from my invention. y Having thus described my inventhm, what l claim is- 1. ln a machine of the class described, the combination of a box, a frame comprising curved supporting rockers composed of collapsible sections, and straps suspendinf.; the box from said frame.

2. in a machine of the class described, the combination of a box, a frame comprising curved supporting rockers composed of collapsible sections hinged together, and straps suspending the box from said frame.

ln a machine of the class described, the combination of a box, a frame comprising curved supporting rockers composed of collapsible rockers, collapsible braces for thc rocker sections, and straps suspending` the box from said frame.

4. in a machine ol' the class described, the combination of a frame comprising curved rockers formed of sections hinged together. a brace har for each rocker consisting of members hinged together and hinged to the rocker sections, a rotatable body, and straps suspending said body from the rockers.

5. ln a machine of the class described, the combination of a rotatable body, a rocking support therefor, stre ps connected with said support, and trunnions on the body composed eaeh of a tube having a filling block, the tube and iilling block being slotted, and the end of the straps being folded and seated in the block, and a pin at they bend of the straps.

6. ln a machine of the class described, thc combination of a rotatable box, a rocking frame, straps connecting the frame. and the box at opposite sides of the latter, and inorable parts on the box movable into and out of contact with the straps, whereby the box is prevented from turning.

7. ln a machine of the class described the combination. of a rotatable box, a rockingl frame, straps connecting the frame and the box at opposite sides of the. latter, a removable cover for thc box, and balls hinged to the box and movable from a position above the cover to a position in contact with the straps.

3. in a machine of the class described, the combination of a rotatable box, a rocking frame, straps suspending the. box from thc frame, and strap-holding means comprising a clamping bar having corrugated strapengaging surfaces.

in testimony whereof l allix my signature in presence of two witnesses.
